Trying to open tightly sealed boxes can be particularly annoying without the right tools around. How many of us walk around with razor blades at the ready? And if you try the task with your fingernails, the injuries can be pretty painful. (Believe me, I've been there. I used to work at Gap, unpacking boxes of denim.)

So this week's innovation pick is the Rip Cord. It's a cord embedded into packing tape that makes the tape easier to pull off a box, and subsequently makes boxes easier to break down. The Rip Cord's string is stuck to tape in such a way that the cord rests in the gap of a box's flaps. To open a box, pull on the cord, and it easily rips the tape at the box's seam.

This is not unlike the seals of those cardboard FedEx or UPS envelopes, which have a tab you can pull to easily rip open the letter package.

An Ohio-based man, Jay Andress, came up with the box-opening idea and pitched it on Quirky, a site where you can submit your invention idea and the community decides whether it should actually be made.

The creator's planet-loving pitch kept recycling at its core. Businesses get lots of packages and if they can't be easily flattened, they may not get recycled. So Andress hopes that making it easy to take boxes apart will make recycling much easier, too.

The Rip Cord is now in development but not yet available for sale. It's expected to sell for about $10 a roll, whenever it comes out.
